Active intravenous drug use during chronic hepatitis C therapy does not reduce sustained virological response rates in adherent patients.

SUMMARY: Reluctance has been expressed about treating chronic hepatitis C in active intravenous (IV) drug users (IDUs), and this is found in both international guidelines and routine clinical practice. However, the medical literature provides no evidence for an unequivocal treatment deferral of this risk group. We retrospectively analyzed the direct effect of IV drug use on treatment outcome in 500 chronic hepatitis C patients enrolled in the Swiss Hepatitis C Cohort Study. Patients were eligible for the study if they had their serum hepatitis C virus (HCV) RNA tested 6 months after the end of treatment and at least one visit during the antiviral therapy, documenting the drug use status. Five hundred patients fulfilled the inclusion criteria (199 were IDU and 301 controls). A minimum exposure to 80% of the scheduled cumulative dose of antivirals was reached in 66.0% of IDU and 60.5% of controls (P = NS). The overall sustained virological response (SVR) rate was 63.6%. Active IDU reached a SVR of 69.3%, statistically not significantly different from controls (59.8%). A multivariate analysis for treatment success showed no significant negative influence of active IV drug use. In conclusion, our study shows no relevant direct influence of IV drugs on the efficacy of anti-HCV therapy among adherent patients.

Politica Nacional de Saude

Na sub-região da África ocidental, Cabo Verde está entre os países com melhores indicadores de estado de saúde da população, graças a um esforço perseverante levado a cabo desde a independência, com a criação de infra-estruturas, a formação de quadros, a organização de serviços, a disponibilização criteriosa de recursos e uma legislação que suporta a institucionalização do sistema de saúde. Num país insular, pequeno e com parcos recursos financeiros, não foi fácil chegar a esse nível de realização. O carácter montanhoso da maioria das ilhas, a exiguidade da população e a dispersão das comunidades rurais em localidades isoladas, por vezes de difícil acesso, acrescido da inadequação dos meios de transporte de massa, marítimos sobretudo, aumentou as dificuldades na busca de soluções aos problemas de saúde dos cidadãos.

Quoi de neuf en medecine des voyages? [What's new in travel medicine?]

Les menaces pour la santé des voyageurs proviennent souvent de l'émergence ou de la réémergence d'anciennes et de nouvelles maladies infectieuses. En Amérique du Sud c'est une augmentation des cas de fièvre jaune qui a fait du bruit. A Bornéo, une nouvelle espèce de Plasmodium pathogène pour l'humain a été mise en évidence. Après l'épidémie sur les îles de l'océan Indien, le virus du Chikungunya a causé de nouveaux foyers et ceci même en Europe. La première journée mondiale de la rage a rappelé que cette maladie continue à tuer un nombre important de personnes dans les pays aux ressources limitées. La rage affecte également des personnes de nos pays comme l'illustre deux situations récentes. Finalement, le nouveau Règlement sanitaire international permettra à l'OMS de mieux répondre aux urgences de santé publique de portée internationale. The threats for the health of travellers come often from the emergence or the re-emergence of old and new infectious diseases. In South America an important increase of the number of cases of yellow fever was reported. On the island of Borneo a new species of Plasmodium pathogenic for humans has been identified. After the Chikungunya epidemic that affected the islands of the Indian Ocean, the virus has caused new epidemic foci and this even in Europe. The first World Rabies Day reminded us that this disease still kills a large number of persons in countries with limited resources. Rabies can also affect persons from our countries, as it was illustrated by two recent situations. Finally the new International Health Regulation will allow the WHO to better respond to public health emergencies of international concern

Phylogenetic structures of the Holarctic Sorex araneus group and its relationships with S-samniticus, as inferred from mtDNA sequences

The shrews of the Sorex araneus group, characterized by the sexual chromosome complex XY1, Y2 have been intensively studied by morphological, karyotypical, and biochemical analyses. Nevertheless, the phylogenetic relationships among the species belonging to the araneus complex are still under debate, as different approaches gave often contradictory results. In this paper, partial nucleotide sequences of the mitochondrial DNA cytochrome b gene (1011 bp) were determined for 6 species of the araneus group from Eurasia and North America. We also included in the data set the sequences of Sorex samniticus, whose relationships with the araneus group remain controversial. Three other species representing two major karyological groups were also examined. Both parsimony and distance trees strongly support the monophyly of the araneus group. Sorex sumniticus is significantly more closely related to the araneus complex than to the other species included in the analysis. Based on the branching pattern within the araneus group, an attempt has been made to reconstruct the colonization history of the Holarctic region.

The Swiss Business Elite (1980-2000): How the Changing Composition of the Elite Explains the Decline of the Swiss Company Network

In this paper we analyse the decline of the Swiss corporate network between 1980 and 2000. We address the theoretical and methodological challenge of this transformation by the use of a combination of network analysis and multiple correspondence analysis (MCA). Based on a sample of top managers of the 110 largest Swiss companies in 1980 and 2000 we show that, beyond an adjustment to structural pressure, an explanation of the decline of the network has to include the strategies of the fractions of the business elites. We reveal that three factors contribute crucially to the decline of the Swiss corporate network: the managerialization of industrial leaders, the marginalization of law degree holders and the influx of hardly connected foreign managers.

Alpha rhythm and hypofrontality in schizophrenia

OBJECTIVE: To reveal the EEG correlates of resting hypofrontality in schizophrenia (SZ). METHOD: We analyzed the whole-head EEG topography in 14 patients compared to 14 matched controls by applying a new parameterization of the multichannel EEG. We used a combination of power measures tuned for regional surface mapping with power measures that allow evaluation of global effects. RESULTS: The SZ-related EEG abnormalities include i) a global decrease in absolute EEG power robustly manifested in the alpha and beta frequency bands, and ii) a relative increase in the alpha power over the prefrontal brain regions against its reduction over the posterior regions. In the alpha band both effects are linked to the SZ symptoms measured with Positive and Negative Symptom Scales and to chronicity. CONCLUSION: As alpha activity is related to regional deactivation, our findings support the concept of hypofrontality in SZ and expose the alpha rhythm as a sensitive indicator of it.
